23.10. Best Practices for Thread Safety

Try these first

1. 1.

   What is thread safety?

   Hint

   Think about how multiple threads interact with shared data.

2. 2.

   Give an example of an immutable object in Java.

   Hint

   Consider data types where instances cannot be modified once created.

3. 3.

   What is the primary benefit of immutability in thread safety?

   • Increased performance
   • Reduced need for synchronization
   • Increased complexity

   Hint

   Think about how changing data can lead to synchronization issues.

4. 4.

   True or False: All variables in a Java program must be mutable to be useful.

   • True
   • False

   Hint

   Consider the advantages of objects that cannot change state.

5. 5.

   Identify and correct thread safety problems in a given code snippet using shared mutable state.

   Hint

   Ensure that shared resources are only accessed in a controlled manner.

6. 6.

   Create a small application that implements the producer-consumer pattern using Java's concurrent collections.

   Hint

   Consider how you’ll manage the lifecycle of threads and ensure resources are cleaned up appropriately.
